In 1916, the Zeppelin-Staaken Werke developed a huge long-range bomber in biplane configuration (a so-called Riesenflugzeug), powered by four engines mounted in pairs in two nacelles on either side of the fuselage, with a crew of 7 to 10 people (including two mechanics servicing the engines), designated R.VI.
A total of 18 bombers of this type were built, of which 9 were manufactured at the Zeppelin-Staaken works, and the rest under licence at the Aviatik (6 machines) and Albatros (3 units) factories. They were successfully used for attacks on Great Britain. Only two were shot down by British fighters; the rest were destroyed as a result of forced landings.
The exhibited engine nacelle with two Mercedes D.IVa engines of 260 hp (194 kW) comes from the Zeppelin-Staaken R.VI 36/16 (Alb.) aircraft, produced at the Albatros Flugzeug Werke in 1917. As part of squadron Rfa 501, it carried out bombing raids on Great Britain. Returning from a bombing mission on the night of 7/8 March 1918, it crashed in Belgium.
